/** Make the installer silent. 
  * This functionality is also available as a setting in JExpress.
  *
  * This eliminates the need for the user to 
  * pass the -q switch and the install directory on the command line.
  *
  * The applicationDirectory *must* be set in the installer's properties *before*
  * trying to make the installer silent.

  * Important:
  *  1. This class must be included in the "Before install" field on the Custom panel in JExpress Developer.
  *
  *  2. This class is not dependent on any other custom classes.
  *
  *  3. You must adapt InstallDir constant to the correct install directory.
  *     A silent install can't ask the user for the install dir.
  *
  *  4. If the installer requires additional custom properties, then you must load those properties
  *     and "addProperties" to the getPropertyList().It would be best to set the applicationDirectory
  *     in the constructor, but load/add any additional properties in the setAcitve() method.
